Answer:

Addition reaction.

Explanation:

There are four possible type of reactions in an organic compound, generally.

a) substitution: where a group or atoms substitutes another group or atom. for example reaction of an alkyl halide with hydroxide ion to give alcohol, where hydroxide ion replaces a halide ion.

b) elimination: Where a group or atom get eliminated from a molecule. For example synthesis of an alkene from an alkyl halide by elimination of hydrogen and halogen.

c) rearrangement: Here there is no addition or substitution or elimination but the molecule undergoes some atomic rearrangements to give a stable form.

d) Addition : in this there is addition of a molecule on a double bond.

In the given example the alkene is undergoing addition reaction as hydrogen is being added on it to give saturated alkane molecule.

Answer:

Explanation:

3.

Knowns: 100mL of solution; concentration of 0.7M

Unknown: number of moles

Equation: number of moles = volume * concentration

Plug and Chug: number of moles = 100/1000 * 0.7 = 0.07 mole

Final Answer: 0.07mole

2.

Knowns: 5.50L of solution; concentration of 0.400M

Unknown: number of moles

Equation: number of moles = volume * concentration

Plug and Chug: number of moles = 5.5 * 0.4 = 2.20 mole

Final Answer: 2.20 mole

Which sample of matter is classified as a substance?<br> (1) air (3) milk(2) ammonia (4) seawater
jeyben [28]
A chemical substance has the characteristics that it cannot be separated by physical  methods. Seawater and milk can be separated by sedimentation, and air has different components depending on other aspects (such as elevation). Only ammonia is a substance. (thus it can have a formula: NH<span>3)</span>

The density of gold is 19.3 g /cm cubed The density of iron pyrite is 5.0 g /cm cubed. Is a nugget of iron pyrite and a nugget o
telo118 [61]
If you clear volume in the density equation:

\rho = \frac{m}{V}\ \to\ V = \frac{m}{\rho}

The greater the density the lower the volume. This means, the volume of gold nugget will be smaller than the volume of iron pyrite nugget.

V_{gold} = \frac{m}{\rho} = \frac{50\ g}{19.3\ g/cm^3} = \bf 2.59\ cm^3

V_{iron} = \frac{m}{\rho} = \frac{50\ g}{5.0\ g/cm^3} = \bf 10\ cm^3
